Non Slip Diamonds

Diamonds are already one of the hardest natural substances known to science. But combine them with graphene, and diamond nanoparticles are also incredibly slippery, which can be useful if you want to reduce friction in a moving machine.
Scientists at Argonne National Laboratory recently announced that the combination of tiny bits of diamond with the two-dimensional graphene created tiny structures that had superlubricity–meaning that the friction between them and another object dropped to near zero.
